NewScientist has an article announcing that the Global Hawk pilotless plane will get to fly routinely in civilian airspace. The Global Hawk has the ability to see and avoid other aircraft and it will be flying at altitudes above 60k feet which is well above commercial traffic so the FAA gave in and approved it for civilian airspace. Previously the USAF had to file a flight plan 30 days in advance with the FAA, now they can file and fly the same day. So, look up in the sky, it's a bird, it's a plane, it's a robot pilotless airplane flying overhead in civilian airspace. Did you ever think you'd see the day where pilotless robot airplanes would share civilian airspace with human piloted airplanes?
